What the company blog doesn't mention, however, is the 2011 intern dance mob: In a YouTube video posted Wednesday starring Microsoft intern "Lena" as dance instructor, Microsoft employee "Joe" as motivator, and a game seven-person dance crew, this year's interns are expected to perform a coordinated dance routine at the company's July 28th "intern party" to the tune of the Black Eyed Peas' "This Time (Dirty Bit)."

According to the video, which includes the description "DANCE MONKEYS DANCE", the "dance mob" routine features classic moves like the "Jersey Shore fist pump" and "Hand bike" ("Turn to the right and bicylce with your hands, then turn to the left and bicycle with your hands," explains Lena).

"We'd like to see a dance mob at the intern event," says Joe, a self-described "full time employee here at Microsoft" in the video. "What I want to see is the music starts, everyone knows the dance and everyone does it at the same time--kind of linke a flash mob--and we'll video tape it and you can the take the video back to your school when you're done."

The YouTube clip appears to be an instructional video for the company's interns. First, Lena, who says she's been asked to help choreograph, walks through the nine key dance moves. Next, she demonstrates them with seven other people in a gray-carpeted conference room (the demo begins about 4 minutes).

You won't want to miss seeing the video for yourself. If you want to practice too, here are Microsoft's nine dance mob moves:

"On July 28th Microsoft will have its annual intern party in Seattle," a Microsoft spokesperson told The Huffington Post in a statement. "There are more than 1000 interns from top worldwide universities that work on all kinds of technologies from Azure to Xbox. Interns bring new energy and ideas every summer and a number of them come back as full-time employees once they’re out of school. In the coming school year, Microsoft will actively recruit from more than 200 universities."
